Safety Considerations
Warning: Before performing service or maintenance op-
erations on a system, turn off main power switches to the
equipment. Electrical shock could cause personal injury.
Installing and servicing heating and air conditioning equip-
ment can be hazardous due to system pressure and elec-
trical components. Only trained and qualified service
personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform
the basic maintenance functions of cleaning coils and clean-
ing and replacing filters. All other operations should be
performed by trained service personnel. When working on
heating and air conditioning equipment, observe precau-
tions in the literature, tags and labels attached to the unit
and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use a quenching cloth for brazing operations and
have a fire extinguisher available.
Note: Local codes and regulations take precedent over
any recommendations by the manufacturer. In addition to
conforming to manufacturer’s and local municipal building
codes, the equipment should also be installed in accordance
with the National Electric Code and National Fire Protection
Agency recommendations.
